This is not as Sungha play but this version sounds exactly like Sungha's.
You need a capo on the 5 freth to make it sound like Sungha.
This is done by ear. This tab is not 100% correct so you should listen to Sungha Jungs 
version first and then play along.
I hope this helped please rate the tab please :)
